Overview

paypal-ipn uses the test_ipn parameter (which is set by the PayPal IPN simulator) to determine if it should use the production PayPal site or the sandbox.

"With a bit of time, an attacker could craft a request using the simulator that would fool any application which does not explicitly check for test_ipn in production." [1]
